HAND LEVER.

Application filed November 4, 1919. Serial No. 335,725.

, To all whom it may concern:

Be it known that I, CONRAD ESPING, a citizen of the United States, residing at Moliue, in the county of Rock Island and State of Illinois, have invented certain new and useful Improvements in Hand Levers, of which the following is a specification, reference being had therein to the accompanyin drawing.

Ihe invention relates to hand levers.

Its general object is to provide an improved hand lever made of a minimum number of parts and in such a way that the cost of production will also be reduced to a minimum.

Other objects and advantages of the invention will appear from the specification and drawings.

In the accompanying drawings:

Fig. 1 is a perspective view of a hand lever embodying my invention. 1

Fig. 2 is a longitudinal sectional elevation laterally to form a lateral hand piece 2 having a hole 3 formed therethrough near its outer end. Adjacent the hand piece, the lever bar is formed with an outer longitudinal guiding slot/1, and adjacent its inner end it is formed with a similar inner guiding slot 5. Extending along one side of the lever bar closely thereto so as to receive guiding support therefrom, is a latch rod 6 which is bent laterally at its outer end so as vto form a lateral portion 7 which extends loosely through and is guided in the outer guiding slot 4 and at its inner end the rod is bent laterally to form an arm 8 which extends loosely through and is guided in the inner slot 5. This arm terminates in a looking latch 9 which is adapted to engage in the open slots 10 of a segment frame 11. The lateral portion 7 of the latch rod extends along the inner side of the hand piece 2 of the lever bar in position to be grasped bythe hand grasping the hand piece, and at its to be employed.

outer end the lateral portion is bent so as to ,ant grasps the hand piece 2 and includes in his, grasp the lateral portion 7 of the latch rod, and in tightening his grasp, the latch rod will be drawn outwardly, thereby compressing the spring and withdrawing the locking latch from the notch in the segment frame with which it was engaged; The lever isthen moved forwardly or backwardly to operate the connected parts, and when theproper adjustment has been secured, the lateral portion 7 of the latch rod is released by the hand, and the spring in reacting will seat the locking latch in another notch in the segment bar. z

The inner end of thelever may be. vari- =ously formed and constructed to enable it to be properly mounted according to the particular type of mechanism with which it is In" the accompanying drawings I have shownone application of the lever, namely, to operate the rocking tooth bars of a harrow. Referring to Fig. 3, a series of tooth bars 15 carrying harrow teeth are mounted to rock between end frame bars 16, only one of which is shown, the several barrow bars having fixed thereto crank arms 17 to which is connected a reciprocating actuating rod 18. In applying my lever to a construction of this form, the lower end of the lever bar is formed'with a foot 19 which is bolted to the forward harrow bar, and the lever bar above the foot is pivoted as at 20 to the forward end of the recipromanifest however that my invention is not I latch'rod mounted thereon, and the spring the claims.

I claim is controlling the latch rod. As a result, the comparatively great number of parts characteristic of the prior construction above pointed out, are dispensed with,'and the expense of production is consequently-greatly lessened. v I

' the foregoing description and accompanying drawings, Ihave set forth my invention in the particular detailed" form which I prefer to adopt and which in practice has'been found to answer to a satisfac- -tory degree the ends to be attained. Itwill be manifest, however, that these details may be variously changed and modified without departingfrom the spirit of my invention;

and further, itiwill be'understoo d that the invention is not limited to any particular form or construction-of the parts, except in so far as such limitations are specified in Having thus described my invention,-what 1. A hand lever comprising a lever bar having a laterally projecting a hand piece provided with an opening therethrough, a

latch rod having a lateral'fhand piece provided with a bent end insertable through the holef-in the lever hand piece, and a spring surrounding the bent end of the latch rod serving to bias it to a latchedposition.

2. A'hand lever comprising a lever bar formed of a single strip of metal one end of which is bent to'form a lateral hand piece,

a toothed sector formed of a single strip of met'al, a latch rod formed of a single metal bar bent so as to provide'at one end a handle 7 portion cooperating with the hand piece of the lever bar and at the other end a latch portion formedto cooperate with thetootlied sector, and a spring between the two handle portions serving to bias the latch rod to' engagedposition. i

3. In a hand lever, the combination of a lever bar formed with-innerand, outer longitudi'na'l guiding slots'and' having at its outer end a lateral hand piece, and a latch rod extending longitudinally along theside of the'lever bar and formed at its outer end with lateral portion extending through and guided in the outer'slot and disposed adjacent-the hand piece'in position to be grasped by the hand in graspingthehand piece, said latch rod being providedet its inner end with a lateral arm extending gitudinal guiding slotsgbent 'itsouter end to form ah'andpiece'having athrough and guided in the inner slot and terminating in a locking latch.
